📋 NAME

debconf-copydb - copy a debconf database

🚀 Quick Reference

Use Case	Command	Description
🔁 Copy all items	debconf-copydb configdb backup	Copy all items from an existing database to another (possibly converting formats)
🎯 Copy by name pattern	debconf-copydb sourcedb destdb --pattern='^slrn/'	Copy only items whose names match the given pattern
🏷️ Copy by owner pattern	debconf-copydb sourcedb destdb --owner-pattern=pattern	Copy only items whose owners match the given pattern
📦 Inline DB config	debconf-copydb configdb newdb --config=Name:newdb --config=Driver:File	Define a database on the fly without a config file
🌐 Remote copy via pipe	debconf-copydb configdb pipe --config=Driver:Pipe | ssh remotehost debconf-copydb pipe configdb --config=Driver:Pipe	Copy a database to a remote system using the pipe driver
📤 Dump to stdout	debconf-copydb configdb stdout -c Name:stdout -c Driver:Pipe -c InFd:none --pattern='^foo/'	Output all items matching a pattern to stdout

🔍 SYNOPSIS

debconf-copydb sourcedb destdb [--pattern=pattern] [--owner-pattern=pattern] [--config=Foo:bar]

📖 DESCRIPTION

debconf-copydb copies items from an existing debconf database into another, possibly new database. The two databases may have different formats; if so a conversion will automatically be done.

⚙️ OPTIONS

• sourcedb
  📛 The name of the source database. Typically it will be defined in your debconf.conf (or .debconfrc) file.
• destdb
  📛 The name of the destination database. It may be defined in debconf.conf or .debconfrc, or you might define it on the command line (see below).

🎯 Pattern Options

• -p pattern, --pattern pattern
  🔍 If this is specified, only items in sourcedb whose names match the pattern will be copied.
• --owner-pattern pattern
  🔍 If this is specified, only items in sourcedb whose owners match the pattern will be copied.

⚙️ Configuration Options

• -c foo:bar, --config Foo:bar
  🛠️ Set option Foo to bar. This is similar to writing:

  Foo: bar

  In debconf.conf, except you probably want to leave off the space on the command line (or quote it: "Foo: bar"). Generally must be used multiple times, to build up a full configuration stanza. While blank lines are used to separate stanzas in debconf.conf, this program will assume that Name:dbname denotes the beginning of a new stanza.

💡 EXAMPLES

• Copy all items to backup

  debconf-copydb configdb backup

  Copy all of configdb to backup, assuming you already have the backup database defined in debconf.conf.

• Copy slrn data with inline config

  debconf-copydb configdb newdb --pattern='^slrn/' \
        --config=Name:newdb --config=Driver:File \
        --config=Filename:newdb.dat

  Copy slrn's data out of configdb, and into newdb. newdb is not defined in the rc file, so the --config switches set up the database on the fly.

• Dump package items to stdout

  debconf-copydb configdb stdout -c Name:stdout -c Driver:Pipe \
        -c InFd:none --pattern='^foo/'

  Spit out all the items in the debconf database related to package foo.

• Remote copy via SSH pipe

  debconf-copydb configdb pipe --config=Name:pipe \
            --config=Driver:Pipe --config=InFd:none | \
      ssh remotehost debconf-copydb pipe configdb \
            --config=Name:pipe --config=Driver:Pipe

  This uses the special purpose pipe driver to copy a database to a remote system.
